The preparation of ester heterocycles mostly uses heteroatoms as nucleophilic sites, which are achieved by intramolecular substitution or addition reactions. Compound: 5,10,15,20-Tetrakis (4-methoxyphenyl)-21H,23H-porphine cobalt (II)( cas:28903-71-1 ) is researched.Quality Control of 5,10,15,20-Tetrakis (4-methoxyphenyl)-21H,23H-porphine cobalt (II).Chambers, Dana R.; Juneau, Antoine; Ludwig, Cory T.; Frenette, Mathieu; Martin, David B. C. published the article 《C-O Bond Cleavage of Alcohols via Visible Light Activation of Cobalt Alkoxycarbonyls》 about this compound( cas:28903-71-1 ) in Organometallics. Keywords: alc carbonylation homolysis reaction porphyrin cobalt; crystal structure porphyrin cobalt alkoxycarbonyl; mol structure porphyrin cobalt alkoxycarbonyl. Let’s learn more about this compound (cas:28903-71-1).
A strategy for the activation of C-O bonds in alcs. via a carbonylation-homolysis-decarboxylation process is described. Using readily available Co(II) porphyrin precursors, carbonylation of simple alcs. provides access to alkoxycarbonyl Co(III) complexes. Spectroscopic, crystallog., and computational methods were used to provide structural details and an estimate for the Co-C bond dissociation energy of an alkoxycarbonylcobalt(III) complex of 39.8 kcal/mol for the 1st time. Visible light irradiation in the presence of the radical trapping agent TEMPO and a thiol reducing agent demonstrates the cleavage of the alc. C-O bond under oxidative and reductive conditions, resp. Addition of a stoichiometric reducing agent allows the use of a catalytic amount of hindered thiol for the reduction of a benzylic alc. to the corresponding hydrocarbon.
